Case study / Foundation
Liahona — LIA
From local needs to architecture: product vision, journeys, data modeling and technical decisions to connect talent and opportunities in Mambucaba.
Problem and user
Connecting opportunities, services and people requires understanding the community, its trust relationships and local talent before building a platform.
My role
Research, product vision, domain modeling and foundation documentation.
Delivered scope
- Product vision, personas and indicators for Mambucaba
- Nine user flows: registration, services, jobs, reviews and communication
- Data model, API specification and ten architecture decision records
- Epics, user stories and foundation sprint planning
- Community employment
- Local services
- Trust between participants
- Talent-pool conception
Constraints
- No product is in production yet
- The implementation stack is planned, not demonstrated in product code
Architecture and data flow
The documentation foundation is complete. React, React Native, Node.js, Prisma and PostgreSQL appear only as planned architecture for a later stage.
Decisions and trade-offs
Document the community, trust relationships, opportunities and services before promising a finished platform.
Tests and validation
Review of the documentation foundation, product artifacts and scope recorded in the repository.
Current state
Documentation foundation completed; no product is in production yet.
Known limitations
- No product implementation is in production.
- Planned technologies must not be presented as delivered.
Next steps
- Validate needs with the Mambucaba community
- Prioritize the first employment and services scope
- Define an MVP based on local evidence
